大叔

Despite that his full name is never revealed throughout the story (his family name is Satou), he's a key character throughout the beginning of the game. He works as an illegal doctor accepting everyone who comes to him for help. His daughter was killed by a jinyou and his wife committed suicide soon after, thus he despises them passionately. As soon as he found out that Takebe Ryouichi is also a jinyou all of his kindness (or more like naiveness) has vanished without a trace. Later on he entrusts him with money, and explains them about Kamizawa. In the end Suzu using her own powers erased the memories that they ever met.
